We decided to go through Costco's program to upgrade our HVAC system (that didn't have A/C!) to a heat pump after going through an extremely hot summer. What a great decision, and part of what made it great is Brennan Heating & Air Conditioning! Installation was completed on time and with great care. The system has provided us with both heating and air conditioning that is much quieter than the old HVAC unit, consistent, and responsive when we need a little extra heat or cooling, and with a UV air purification component.
Brennan's service has been stellar, performing annual maintenance, duct cleaning, thoroughly checking all of the systems, and responding promptly when a problem popped up - ice formed during a cold, rainy snap (not due to equipment malfunction - rather due to needing a little protection from the rweather). Their customer services reps are quick to respond when contacted. Our most recent maintenance was performed by Dom - a polite young man who was respectful in our home and really provided excellent, knowledgeable service.

James came out and did a fantastic job. I have an older unit and he cleaned and checked everything thoroughly. Pictures were taken and he explained things so that I could understand them. If anyone needs heating, electrical, plumbing or air work done give Brennan a shout. You won't be disappointed!

I've been a customer of Brennan Heating for several years. They serviced my original furnace and water heater and eventually installed replacements for each. All service calls were done promptly and professionally, and the most recent one. with Brad, was especially pleasant and appreciated. My only suggestion for improvement would be to step up your senior discount, as I and many homeowners are retired seniors on fixed incomes, and any discounts are welcome. Otherwise, wonderful company and services!

We can’t say enough great things about our experience with Brennan Heating & AC, and the extremely nice technician, Joseph Rodriguez! He explained the process, was so personable with my husband to discuss the football, and then showed us photos of how extremely dirty our dryer vent was. We’re extremely thankful that your company keeps our dryer vent clean & safe to prevent a fire! We setup a reminder on our iPhone calendar to request this service every three years. We look forward in working with your fabulous company and staff in the future. We’re DEFINITELY going to recommend you to our neighbors and friends. We also appreciated the text stating when Joseph was on his way and providing his name, so that we could make him feel welcome at our home! We wish your company much success!!!

We had a Brennan technician come out to clean and service our 18-year-old furnace to get ready for winter, and we are very pleased with the overall experience. Making the appointment was easy and the office did a good job of sending reminders and giving us updates on the tech's arrival time. Reginald Denson, the technician, was prompt, friendly and very knowledgeable about our furnace. He spent several minutes explaining the key components of the system, which ones were likely to fail as our furnace reaches the end of its life span, and how much it would cost to repair or replace the unit. We would definitely recommend Brennan's service team!
